LAMP-EXTINGUISHER.

SPECIFICATION forming part of Letters Patent No. 484,362, dated October11, 1892.

Application filed May 5, 1892. Serial No. 431,943. (No model.)

To all whom it may conccrm.

Be it known thatI, MAX GOETZE, of Sturgis, in the county of Meade andState of South Dakota, have invented a new and usefulLamp-Extinguisher,of which the following is a full, clear, and exactdescription.

This invention relates to an improved safetyextinguisher for hand andstand lamps, and

has for its object to provide a novel, simple attachment for a lamphaving a flat wicktube which will automatically cover the top of such awick-tube in the lamp and extinguish a lighted wick therein if the lampis overturned or dropped and its chimney displaced or broken.

To this end my invention consists in the peculiar construction andcombination of parts, as is hereinafter described and claimed.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar letters of reference indicatecorresponding parts in all the figures.

Figure 1 is a side View in section of a lamp-i burner, a chimney brokenaway above, and

the improvement in place on the burner in section, taken on the line 1 1in Fig. 2. Fig. 2 is a plan view of the lamp-burner, a chimney insection, and the extinguisher on the burner. Fig. 3 is a side view insection of the lamp-burner, chimney broken, and extinguisher, taken onthe line 3 3 in Fig. 2. Fig. 4 is a broken detail view in perspective ofpart of the lamp-burner and the improved extinguisher thereon brokenaway below and in closed adjustment, and Fig 5 is a detached perspectiveView of an essential feature of the improvement.

The lamp-burnerA is of ordinary approved construction adapted to retainthe glass chimney B in place on it by the stress of the bow springs a,that bear upon the exterior surface and lower part of the chimney whenit is lo-- cated properly upon the gallery 00 of the burner. A flatwick-tube b is a necessary part of the lamp-burner whereon theimprovement is applied, and projects in the usual manner above and belowthe perforated diaphragm c of the burner, whereon a cone deflector (notshown) of common construction is seated so as to inclose the wick-tubelaterally above the diaphragm when the burner is ready for service, saidcone deflector being omitted from the drawings to avoid obscuring thefeatures of improvement.

The wick-extinguisher that embodies the improvement consists,essentially, of two rocking gates d that are substantially alike, eachgate having at its ends depending limbs d, which in one gate overlap thelimbs of the other gate, each pair of these lapped members being pivotedupon asmall pintle-arm, which arms f are affixed to the diaphragm-platec opposite the edge walls of the flat wick-tube b, so that the boxed topportions of the gates when rocked together willinclose the top of thewicktube, one gate sliding within the other when so adj usted. There isa peculiarly-bent lever 6 .bent wire. portions joined at each end afterthe lever is in position on the burner A. The

wire strand forming the lever e is first bent near its center so as tofold the same at e and produce parallel members. These are bentlaterally at e and then again in a re- .verse direction at e so as todispose the spaced strands in a plane nearly parallel with the portionsnear the bend 6'. At 6 the two strands of the lever are bent nearly at aright angle away from the parts between this bend and the folding-bendc.

There is such a proportionate length given to the portions of the levere which extend beyond the bends e as compared to the width of thegallery and diaphragm-plate c of the burner A that these strands wheninserted through adjacent holes in the raised edge of.the gallery at,until the bends e are nearly in contact with this circular edge, willextend across below the diaphragm-plate on each sidezof the wick-tube b,and at e where upwardly bent, project through spaced holes in saiddiaphragm, as shown in Fig. 1.

The strands of the lever e, that loosely pass through thediaphragm-plate c, are at a proper distance from the bends 6 again bentoutwardly from the wick-tube into a plane parallel with thediaphragm-plate, as at 6 and near said bends the end portions of theleverstrands are bent toward each other and united, thereby completingthe lever and locating it in a proper position on the burner body.

A spring-wire lifter-arm g is furnished as a means to raise the gates dand close their boxed upper portions above and near to the upperterminal of the wick E in the wick-- tube b, which arm is in the form ofan elongated loop that encompasses the wick-tube, and has its endportions g wrapped spirally upon a transverse rod h, the outer terminalsof these springs being afiixed. to the diaphragm c, as shown in Figs. 1and 4. The bow portion of the looped-wire arm projecting toward theadjacent cross-piece of thelever e, that is embraced between the bendse, is thereto secured so as to adapt the force of the spring to liftthis end portion of the lever e and simultaneously elevate the gates atby a sliding contact of the looped arm upon the limbs d of the gates.

The boxed gates d are weighted on their sides, as at d said weightsbeing sufficient to quickly rock the gates outward and downward whenthey are released, and to efiect their liberation from the embrace ofthe looped lifter-arm g it is only necessary to press the uprightportion inwardly where looped at e, which will rock the other endportion of the lever downwardly, and the attached end portion ofthe armg also, thereby disposing the spaced members of said arm, which lie eachside of the wick-tube, in a horizontal position near to the top surfaceof the diaphragm-plate c and below the limbs d of the gates, so that thegravity of the latter will throw them into the position shown in Fig. 3,

In use the placing of the chimney B upon the lamp-burner A'Will causeits inner surface to press the bent upright portion of the lever e at ethus causing the opposite end of said lever to be rocked downwardly andoffecting a release-of the weighted gates d, that fall open and permitthewick E to be lighted.

If by accident'the lamp having the improvement is overturned so as toremove the chimney B or break it in a manner that will release theengaged end portion of the lever e, said lever will be thrown into theposition shown in Fig. 3 at its opposite end by the stress of the coiledsprings on the arm 9,

(which arm by its elevation will instantly close 1. Alamp-extinguishercomprising two pivotally-supported and weighted gatesthat will inclose the upper end of awick-tube, a bowed arm one end ofwhich is adapted to lift the gates and close them, and a bent leverextended across the burner-body that when depressed at one end will holdthe bowed arm away from the gates, substantially as described.

2. The combination, with a lamp-burner having a flat wick-tube, of twoweighted pivoted gates boxed at their upper ends and adapted to inclosethe top of the wick-tube, a bowed spring-arm embracing limbs of thegates and holding said gates normally elevated, and a bent lever holdingthe springarm depressed when pressed by a lamp-chimney at one end,substantially as described.

3. The combination, with the body of a lamp'burner and a flat wick-tubetherein, of two gates boxed at their upper ends and each having twodepending limbs at their lower ends, weights on the gates, a loop-shapedarm spring-pressed upwardly and embracing the limbs of the gates, and alever bent double from a wire strand and embracing the wick-tube, oneend portion of said lever projecting to impinge upon a lamp-chimneyseated on the burner-body and its other end engaging the end of thespring-arm, substantially as described.

4. The combination, with the body of a lamp-burner and a flat wick-tubetherein, of two boxed gates, weights on the gates, two depending limbsfor each gate lap folded in pairs at their lower terminals, pintle-armsloosely engaging the perforated lower ends of the gates, a loopedlifter-arm embracing the wick-tube and gate-limbs, spiral springs on thelimbs of the lifter-arm, having their terminals secured to theburner-body, and a double-strand lever passing across the burnerbody andfulcrumed therein near one upright end portion of the lever, which endportion is adapted to impinge upon the inner face of a seatedlamp-chimney and elevate the other end of the lever that is attached tothe spring-pressed arm, substantially as described.
